Hello there,
I live in an area with very spotty reception. I am not sure what I did or how I did it but my phone will ONLY connect to 4g. If there is no 4g service then I have no service period. I can be sitting next to my family and I have no service and they will have 2 or 3 bars of 3g or even sometimes 1x. We have travelled to areas of 3g service and I will lose service completely. Basically it is like my phone it set to LTE only. This also means that I cannot make a phone call with the HD calling setting turned off. My phone is not connecting to any of the alternative voice services, just 4g. I have removed my sim and had no success. Thank you for any info
